v DETAGHVABLE HEEL.

' applicati@ eied'otober 13, 1927;v serial No. 225382. n

My invention relates to an improved form of detachable heel for shoes, by which heels of rubber may readily be placed on shoes' equipped to receive them andV readily removed without the use of tools of any. kind. My construction further provides that the heels of the right and left shoes of-any pair `may be interchanged as desired to equalize lwear, and that the retaining devices are en` tirely concealed when the heels are locked place on the shoes. v

My invention will best be understood by reference to the accompanying drawings showing a preferred embodiment thereof in which r.

Fig. 1 illustrates a part of a shoe in side elevation with my heel in place thereon,

Fig. 2 is a sectional view to an enlarged scale, of the parts shown inFig. 1, taken along the line 2-2.

Fig. 3 is a plan view of the parts shown in Fig. 2 with the shoe removed and with the heel in section to show part 'of theretaining anchors employed, and

Fig. 4 is a rear elevation ofthe retaining,`

devices shown in Fig. 3, with the material of the heel shown in section toymore clearly disclose Athe retaining devices.

Similar numerals referv to similar parts Asshown in Figs. 2,3 and 4 my construcl tion consists of a plate 10 to be securedto the heel portion 11ofa shoe lby screws 12,

thev edges of the plate 10 indicated at 13, 13.

beingofreduced'thiclrness to form tongues entering corresponding grooves formed .in Vthe inner edges of retaining members 14, 1'4

'7 provided with anchorsl and 16 embedded inthe material of the heel 17. As indicated in Fig.- 3, the retaining members -14, 14 ex-rv tend throughout the length of the heel 17 p and are curvedat their rear ends tothe conformation o'f the rear end lofthe plate 10,

and as more clearlyl shown in Fig.V 4, one of the members `14 is provided at its 4rear end with av projecting tongue 18 enteringa corresponding end groove 19 in the other retaining member 14. lThis tongue and groove engagement permits a hinge action at the rear end of the retaining members-for a purpose 'to be described. The anchors 15 extend outfwardlyfrom each of the members 14 and are embedded in the materialof the heel '17 bers 14.AL A

inwardly `to vduistribute the engagement *be-p tween the material of the heel andthe mem-- Each ofthe members 14isprovidedin its edge groove with a projecting lug 20ffor v entering a corresponding notch 21 in the edge'of one of the tongues 1 3 when the heelis 1n place on the shoe.- e A thin wall 22 of the heel 17 is continued above the front ends of the plate 10 and the members 14 toconceal these parts whenfthe heel is in place on the lshoe as shown in Fig. 1. i. *a f' The material of the heel may be of any convenient kind for the purpose, for example `rubber compound, the lprincipal requisite being thatit shall have sufficient resiliencer to serve as a cushion heel4 and at the Sametime permit suicient separation of the members 14 from each other at their front ends when the 'heel is slid onto theplate 10, to permit the lugs 20 topass over the outer edges of the tongues-13 and engage the notches'21,

the heelr are sprung outwardly vat their front end. to sufficiently' release the lugs 20- fromy the nothe'sV 21 when'the heel maybe slid rearwardly from the plate 10.

extend from the ,side edges of the.V plate 10 around its rear end yand'that theV grooves inthe members 14 are similarly formed, as a result of which when the retaining memon the plate 10, to hold the heel on the shoe, the retaining members are securely held in Vsubstantially the plane of the plate 10 and thus lat-eral l'stiffness and vsupport isA imparted tothe resilient material of the heel`v through the anchors 15 and 16` extending therefrom. The plate and retaining members are preferablyl made of cast'metall of sucient strength and stiffness to perform which engagement locks the heel in place on l the plate 10. For thisuoperation, the thin It-V will be'ob'served that the tongues13?l bers are in the position indicated in Fig.l 3

their intended function, for examplealuminum alloy lor brassThe materialof the heel .171s preferablyso related to the upper surfaces of the'members 14 thatit presses into close engagement with the bottom of the heel portionzofwtheshoe when thev heel is in place on the shoe and thus a practically Water tight joint is produced between the heel and-the shoe when the heel is in use.

It will be observed that the parts of thev devicel are simple and Vcheap in construction and eliicient in use and that when the heels are Worn over on one edge or another they may be interchanged on anypair of shoes and further that When tlieheels are Worn out they may be replaced Without difficulty and Without the use of tools of any kind to remove the heels fromtlie shoes or place them on the shoes.

While Ii have shown my invention in the particular embodiment above-described, kit will be understood'that I do not limit myself to this exact construction as'I may employ equivalents known to the art at the time of the filing of this application Without departing from the scope of ther appended claims. f a I yWhat I claim is: l
